Dan 7.13 “In my vision at night I looked, and there before me was one like a son of man, coming with the clouds of heaven. He approached the Ancient of Days and was led into his presence. 14 He was given authority, glory and sovereign power; all nations and peoples of every language worshiped him. His dominion is an everlasting dominion that will not pass away, and his kingdom is one that will never be destroyed.
So, the Son of Man comes with the clouds of heaven. We see this in Jesus' Olivet Discourse...
Matt 24.30 “Then will appear the sign of the Son of Man in heaven. And then all the peoples of the earth will mourn when they see the Son of Man coming on the clouds of heaven, with power and great glory. 31 And he will send his angels with a loud trumpet call, and they will gather his elect from the four winds, from one end of the heavens to the other."
We see this also in 1 Thes 4...
1 Thes 4.15 According to the Lord’s word, we tell you that we who are still alive, who are left until the coming of the Lord, will certainly not precede those who have fallen asleep. 16 For the Lord himself will come down from heaven, with a loud command, with the voice of the archangel and with the trumpet call of God, and the dead in Christ will rise first. 17 After that, we who are still alive and are left will be caught up together with them in the clouds to meet the Lord in the air.
We see this in the book of Revelation...
Rev 1.7 “Look, he is coming with the clouds,”
and “every eye will see him,
even those who pierced him”;
and all peoples on earth “will mourn because of him.”
I dare say that this presentation of the Son of Man coming with the clouds form the blueprint for NT eschatology in which the Son of Man Comes Again.
When I put all of this together, I think the NT consistently portrays the coming of the Son of Man at the end of the age, when Antichrist is destroyed, and not at the Ascension.
I do see how you may read it, because it appears that the Son of Man 1st approaches the Court of Heaven, the Ancient of Days, before he comes to establish God's Kingdom. And Christ did ascend 1st to heaven, to the right hand of God the Father, well before he will return to set up God's Kingdom on the earth.
But in the Daniel account, the context is all about the 4th Kingdom, which I believe to be Rome, and the evolution of this dual empire into a 10 nation confederation under the Antichrist. So for me, the context is not the Ascension, but the Antichrist.
You may wonder how I skip over this appearance before the Court of Heaven? I do because I believe it is just an explanation of Christ's mission when he returns. He is ordered, in advance, to come back, destroy the Antichrist, recover God's People, and establish God's Kingdom on earth.
He does not interrupt his return to visit the throne in heaven, as I see it. Rather, I believe this is parenthetical as an explanation, to show without any chronological order, the fact he has already received orders. And it shows him actually doing this as if by way of flashback.
Regardless, this is my view and how I justify it. You're welcome to advocate for your position, as well.
